Patented June 24, 1930 STATES PATENT ()FFICE 'GERA'RDO F. -MARCIANO,OFPROVIDENCE, RHODEISLAND, AssIGNoR T UNIVERSAL oP'rIcA'L CORPORATION,OF PROVIDENCE, HODE ISLAND, A CORPORATION OF RHODE ISLAND OPHTHALMIC:MOU-N TING This invention relates to an improved "construction ofophthalmic mounting; and has for its object to provide in such amounting abridge member formed in substantially U- shape having a crossbar with elongated, downwardly-extending side arms curved to conform tothe contour of the inner surface of the eyewires and attached to theeyewires.

A further object of the invention is to extend the side arms down to apoint adjacent a medial line thru the eyewires and each arm having atubular rivet or other fastening by which it is secured to its eyewire.

WVith these and other objects in view, the

invention consists of certain novel features of construction, as will bemore fully described, and particularly pointed out in the appendedclaims.

In the accompanying drawings:

'20 Fig. 1 is a front elevation part-1y in section illustrating myimproved bridge member as connecting together two spaced non-metalliceyewires.

Fig. 2 is an edge view of the construction "2 illustrated in Fig. 1.

Fig. 3 shows the bridge member as detached from the eyewires andillustrating the tubular rivets as connected to the side arms of thebridge.

Fig. 4 illustrates a length of tubular wire which is to be cut intoshort lengths and the lengths being secured at one end to the side armsof the bridge member to serve as attaching rivets.

- F ig. 5 is a fragmental View partly in section illustrating tubularrivets on an arm of the bridge member as extending thru the stock of theeyewires and upset on its inner surface to rivet the arm to theeyewires, the

rivets being widely spaced and located at the opposite ends of the sidearm.

Fig. 6 shows the lower rivet on the side arm as being located on themedial line thru the eyewires.

" Fig. 7 is a View showing the two rivets on the side arm as straddlingthe medial line thru the eyewires.

It is found in the practical construction of ophthalmic mountings, ofadvantage in some instances, to form the bridge member with a cross barlocated substantial distance abovethe medial line thru the lenses andadjacent a line across the upper edges 'of'the eyewires and providedwith elongated downbodiment of my invention and showing means by whichthese advantageous results may be accomplished Y I With reference to thedrawings, 10 designates the eyewires which in this particulariqo caseare shown as being formed of non-metallic material, and 11 designatesthe br id e member which comprises across bar 12, t e

upper portion of which is herein show-n as bei'ng substantially on animaginary line ex- 775 tending between the uppered'ges of the eyewires.

This cross bar is provided with a pair of downwardly-extending side arms13, each of extended length, and inwardly curved to follow the contourof the inner edge of its wire and to set in contact therewith. In orderto fasten the side arms of this bridge member securely to its eyewires,I have soldered short lengths of tubular wire 14, best illustrated inFig.3, to extend laterally from these side arms and have providedcorresponding openings 15 in the eyewires thru which these tubularrivets 14may extend.

The i'nner ends of these rivets are spread against the inner surface-ofthe eyewires to bind and fasten the side arms onto the eyewires.

Inasmuch asthis type of bridge member is not intended or shaped to restupon the nose of the wearer, I have secured a pair of nose guards 16 tothese side arms preferably on a medial'li'ne thru'the lenses, each ofthe'guards being provided with a bendable arm 17 which is'secured 'toits side arm of the bridge mem- 1100 ber preferably at a point adjacentthe medial line thru the eyewires.

In some instances, these side arms 13 may extend down to a pointadjacent the medial line, as illustrated in Figs. 1, 5 and 6, in whichcase both of the rivets are shown asbeing above this medial line, whilein other instances, as best illustrated in Fig. 7, the lower end 18 ofthe bridge arm is extended to a point a substantial distance below thismedial line and the rivets 19 as being arranged to straddle this medialline, but any desired arrangement of positioning these rivets orfastening members relative to the medial line, may be employed.

Theforegoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical evewire and aro ectin fromeach of said o J b arms in the plane of said arms and extending fromsaid eyewires for, binding and securing each arm to its eyewire.

2, An ophthalmic mounting comprising a pair of spaced eyewires, a bridgemember having a cross bar with spaced elongated downwardlyextending sidearms in the plane of said eyewires closely fitting against and curved tofollow the contour of the eyewire and spaced rivets secured to andprojecting from the inner surface of each arm in the plane of said armsand eyewires and extending through said eyewires, and a nose guardattached to each of said arms.

3. An ophthalmic mounting comprising a pair of spaced eyewires, a bridgemember having a cross bar set substantially on a line with the upperedge of the eyewires and having elongated downwardly-extending side armsin the plane of the eyewires and closely fitting the curvature of theinner edges of the eyewires, said side arms having tubular rivetsprojecting therefrom and in the plane of the arms and eyewires extendingthrough the eyewires and upset 0n the inner surface there of, and noseguards attached to said arms adjacent the medial line through theeyewires.

4. An ophthalmic mounting comprising a pair of spaced eyewires, a bridgemember having a cross bar set substantially on a line with the upperedge of the eyewires and having downwardly-extended side arms in theplane of the eyewires resting against and folplane of said eyewirescurved to follow the contour of the eyewire and spaced rivets projecting from the inner surface thereof and in the plane of the arms, anda nose guard attached to each of said arms. v

In testimony whereof I affix my signature.
